Two things. Just two things in your ducts are responsible for giving the blower in your furnace or air handler a hard time. They make the blower push against more pressure, thus reducing air flow or increasing energy use, depending on blower type. They cut the amount of air that gets delivered to the rooms. And they can be reduced but not eliminated. Do you know what they are? The MAF output frequency is a function of the power required to keep the air flow sensing elements (hot wires) at a fixed temperature above the ambient temperature. Air flowing through the sensor cools the sensing elements. The amount of cooling is proportional to the amount of air flow.

To test and debug a MAF application, you generally take the following steps: Test the application's infrastructure, such as a splash screen, application feature navigation, authentication, and preferences, ensuring that all declared application features are available. DegreeC sensor designs draw on decades of airflow engineering expertise and market leadership to provide the best-in-class air velocity sensing capability in a multitude of packages including corrosion-resistant probes, remote head transducers, and board mount sensors.

The job of the mass air flow sensor is to keep track of the amount of air coming in through the air filter, so that the ECU can adjust the amount of fuel getting into the engine. If the mass air flow sensor isn't working properly then you will be faced with one or more symptoms such as lack of power and bad fuel economy. The MAF output frequency is a function of the power required to keep the air flow sensing elements (hot wires) at a fixed temperature above the ambient temperature. Air flowing through the sensor cools the sensing elements. The amount of cooling is proportional to the amount of air flow.
